The University of Texas at Arlington (UTA) Library uses ILLiad to process Demand-Driven Acquisition (DDA) purchase requests. MARC records obtained from the vendor are parsed and massaged with a script that creates an interleaved file of bib and holdings records for import into the ILS. As part of that process, the holdings 856 field is populated with an OpenURL using data from the bib record. When patrons click the OpenURL link in the OPAC, it directs them to UTA's ILLiad instance. After the patron authenticates in ILLiad, the OpenURL data populates a custom ILLiad DDA request form. When submitted, the request is automatically directed to a custom queue for DDA review. Staff can route to additional custom DDA queues (DDA Request Ordered, DDA Request Received, DDA Requestor Notified) as appropriate. A custom email template was created to facilitate notifications to the patron who requested the item.
